cleaning time for 1 house-= 2 hours and 45 minutes

cleaning time for 3 house= 3(2 hours and 45 minutes)

                                               =6 hours and 135 minutes

convert minutes into hours 135/60= 2 hours and 15 minute

now add this time with 6 hours so, it become 8 hours and 15 minutes
